Email Print Outs

I have been having a problem with printing my emails from Outlook Express6 but I am able to print emails from my Yahoo and Sky accounts, my friend has done a check and reckons that there is a file C:\ProgramFiles\AlwilSoftware\Avast4\ashOutXt.dll missing from its program but does not know how to install it. From what I can see I will need to have a CD-ROM to do the job, is this the case and how do I go about it or is the problem something else

Thank you for the reply, what happens is that when I get an email on Outlook Express and try to print it all the printer does is print the top four lines of Who from, Who to,Date sent,Subject. but as I say the other email programs print the full email. I am a bit of a novice at this and so my friend says that he will call in tomorrow to follow it up

If Outlook Express is only printing the header of the mail and no body then you need to open Internet Explorer - go to the View menu and select Encoding. Then clear Auto Select. Now open Outlook Express and try printing again.

Oh Dear because I told my friend that I am going to use Yahoo and Sky mail he only went and took Outlook Express off of my computer so I can no longer use it anyway.
I am annoyed because I did not expect him to do that. I will have to just use the others now unless I re-install Outlet Express at some time. Thanks anyway for your time and info.

Outlook Express is not in the Recycle Bin as this has been emptied lotvic,so how do I find O.E. in the XP program please, like I have said before I an only a novice (75 Years old)and need to be told in a way that I can understand please. I would rather not have to trouble my friend again.

I went to Control Panel,Add&Remove,Set Program Access&Defaults,Custom drop down,Choose default e-mail program and clicked on Outlook Express which then gave me back Outlook Express in the All Programs and I then created Desktop Shortcut. I am now back to square one but the printing of emails is still the same problem with only printing the To,From,Date,Subject at top of print out.So is the problem with Avast Anti Virus?
